7 Claims. 1

This invention relates to hair pins, and particularly to hair pins of the Bobby type known as Bobby pins.

One of the objects'of the invention is the provision of a pin of the above general type that will hold the hair more securely than the conventional structure and without injury to the hair.

Another object of the invention is the pro-Y vision of a hair pin that is economical to make and that is of a structure that will blend with the hair so as to be relatively inconspicuous.

Other objects and advantages will appear in the drawings and in the description.

In the drawings:

Fig. 1 is an enlarged edge View of a pin illustrating the invention.

Fig. 2 is a plan view of the pin of Fig. 1 with a section of the upperleg broken away to show part of the lower leg.

Fig. 3 is an enlarged fragmentary sectional view taken along line 3-3 of Fig. 2.

Fig. 4 is an enlarged fragmentary sectional View of a modification of the pin of Figs. l to 3.

In detail, the pin illustrated comprises a pair of wires I, 2 in side by side relationship and joined at one of their ends as by bending a single length of wire on itself. Their opposite ends are joined in any suitable manner, as by welding, soldering, etc.

The wires I, 2 may have their opposite end portions oppositely twisted, after which said pair of wires may be doubled on itself at an untwisted portion 3 thereof intermediate said twisted end portions in a manner to form a loop at said portion 3 (Fig. 1). In this way a pair of opposed legs 4, 5 are provided, each being a twisted length of said pair of wires l, 2 thus providing transversely extending grooves 6 on the opposed sides of said legs and which grooves are parallel due to the opposite twisting of the wires.

Before the pair of wires are bent to form the loop at 3 the legs extending from the loop and commencing with the twisted portions are ilattened to provide flat surfaces 1 (Figs. 2, 3) between grooves 6. The portion 3 is preferably not flattened, the wires remaining round.

Leg 4, which is the upper leg of Figs. 1, 2, extends slantingly from loop 3 in direction toward leg 5 until it comes into substantial engagement its free end (Fig. 1) and the wires in remainder 8 of said leg from said point to its free end are preferably flattened but untwisted (Fig. 2) and with leg 5 at a point 8 adjacent, but spaced from said remainder 9 extends awayY from leg 5 commencing at point 8.

The leg 4 is slightly shorter than leg 5, and the latter is straight as best seen in Fig. 1. 1

While in most instances the grooves 6 in the opposed sides of legs Il, 5 are preferably opposite each other (Fig. 3) there are instances in which the grooves in one leg as indicated at l0 in Fig. 4 are offset relative to grooves H in the other leg. This is where the hair is relatively fine and thin inasmuch as by this arrangement different strands of hair are in different grooves, and the effect isa doubling of the number of grooves. Where the grooves are opposite each other as seen in Fig. 3 a greater number of strands of hair will be held between each pair oi opposed grooves than in Fig. 4 where the grooves are not opposed to each other, but where the grooves in one leg are opposed to the flat surface libetween the grooves in the other leg.

By the structure shown, there are no sharp edges on the pin to injure the hair and the opposed sides of each groove are convexly curved in cross-sectional contour. The grooves extend across the edges of the legs and across the backs thereof. Thus the grooves on the edges and backs also assist in preventing the pins from accidentally sliding from the hair.

The provision of grooves and convexly sided grooves as well as the double wire loop 3 tends to minimize the visibility of the pin and in the event of light being reflected from the flat surfaces 1 this light is broken up into beads of light that tend to produce a decorative effect that is highly pleasing.

The pins may, of course, be treated in the usual manner to give them any desired color so as to match the hair of the user.

I claim:

1. A hair pin comprising a length of resilient material doubled on itself to provide a pair of .opposed legs between which the hair is to be held, the opposed sides of said legs being provided with opposedly opening grooves extending diagonally of the length of said legs, said grooves on each leg being spaced from each other a substantial distance and the surface of the leg between the grooves on each leg being flat and coplanar,

2. A hair pin comprising a length of resilient material doubled on itself to provide apar of opposed legs between which the hair is to be held, the opposed sides of said legs being provided with opposedly opening grooves extending diagonally of the length of said legs, said legs being flattened on the sides having said grooves formed thereon and the said grooves extending across the opposite edges of said legs and across the oppositely outwardly facing sides thereof.

3. A hair pin comprising a length of resilient material doubled on itself to provide a pair of opposed legs between which the hair is to be held, the opposed sides of said legs being provided with opposedly opening grooves extending diagonally of the length of said legs, said grooves on each leg being spaced from each other a substantial distance and the surface of the leg between the grooves on each leg being iiat and coplanar, the opposite sides of each groove being of `convex cross-sectional contour transversely of. each groove.

4. A hair pin comprising a pair of spring wires in side by side relationship, said pair being doubled on itself to provide a pair of opposed legs, the pair of wires of each leg being twisted to secure the wires together and to provide opposedly opening grooves on said legs extending transversely of the lengths of said legs and diagonally of said lengths, said Wires being partially iiattened on the opposed sides of said legs.

5. A hair pin comprising a pair of spring wires in side by side relationship, said pair being doubled on itself to provide. a pair of opposed legs, the pair of wires of each leg being twisted to secure the wires together and to provide opposedly opening grooves on said legs extending transversely of the lengths of said legs and diagonally of said lengths, said wires being partially attened on the opposed sides of said legs, and the wires of one leg being twisted in a direction opposite to the wires of the other leg, whereby the grooves on said opposed sides are generally parallel,

6. A hair pin comprising a pair of spring Wires in side by side relationship, said pair being doubled on itself to provide a pair of opposed legs, the pair of wires of each leg being twisted ,to secure the wires together and to provide opposedly opening grooves on said legs extending transversely of the lengths of said legs and diagonally of said lengths, said wires being partially flattened on the opposed sides of said legs, the portion of said wires at the bend being round and untwisted.

7. A hair pin comprising a pair of spring wires `in side by side relationship, said pair being doubled on itself to provide a pair of opposed legs, the pair of wires of each leg being twisted to secure the wires together and to provide opposedly opening grooves on said legs extending transversely of the lengths of said legs and diagonally of said lengths, said wires being partially flattened on the opposed sides of said legs, and the wires of one leg being twisted in a drection opposite to the wires of the other leg, whereby the grooves on said opposed sides are generally parallel, one of said legs being shorter than the other and extending away from said other leg for a portion of its length adjacent its free end, said wires of said portion being straight longitudinally of the leg and free from twisting.
